a braking system that uses suction to apply brakes, commonly found in older railway systems
What is a "vacuum brake"?
A vacuum brake is a type of braking system used on some trains, which operates by creating a vacuum, a space with low air pressure, to activate the brakes. The vacuum is created in a chamber and, when applied, causes a valve to open, which allows brake pads to press against the wheels, slowing the train down. This system was widely used in the past, especially on older trains, but has been mostly replaced by air brakes in modern rail transport due to the greater reliability and power of air brake systems. Despite this, vacuum brakes are still found on some older or preserved trains.
Example
Maintenance of the vacuum brake system requires specialized knowledge and regular checks to ensure optimal performance.
The vacuum brake became a standard feature in railways during the 19th century, improving safety and efficiency in train operations.
When the vacuum brake is engaged, it creates a vacuum in the braking system 's pipes, allowing atmospheric pressure to push brake blocks against the wheels.

Modern trains have largely replaced vacuum brakes with more advanced air or electronic braking systems for enhanced reliability and control.
Trains equipped with a vacuum brake system rely on air pressure differences to slow down and stop the locomotive.
